Designed for versatility, the ENERGI Sliding Power Case enables users to charge, sync, transfer data and listen to music on their Galaxy S4 - all while charging on the go. The unique battery sleeve, which only adds 9mm to the S4's thickness, easily slides off to reveal a slim-line protective case that comes in both black and your choice of blue, red or green.

"We designed the ENERGI Sliding Power Case to give users more flexibility when using a charging case," said Kannyn MacRae, Director of Product Development at TYLT. "Not only is the battery case extremely sleek, but it comes with two lightweight cases for instant customization. This powerful case provides more than enough extra juice to satisfy any moderate to heavy battery user."

The ENERGI Sliding Power Case does not interfere with the S4's NFC functionality and comes with a micro-USB cable for charging. The battery sleeve also features an LED light that indicates remaining battery capacity.

The ENERGI Sliding Power Case for the Samsung Galaxy S4 is available now for $99.99 at www.tylt.com. Click here for hi-res images. An iPhone 5/5S-compatible version is currently available as well.
